finish_bulk_checkin() stores the checksum from finalize_hashfile() by writing to the `hash` member of `struct object_id`, but that hash has nothing to do with an object id (it's just a convenient location that happens to be sized correctly). Store the hash directly in an unsigned char array. This behaves the same as writing to the `hash` member, but makes the intent clearer (and avoids allocating an extra four bytes for the `algo` member of `struct object_id`).
